No such thing as an "LXXXX" code. P codes are powertrain, B are body, C are
chassis and U codes are network codes.

I have however, seen people think the "odometer trick" actually means a
whole bunch... can't speak for anywhere else but I have yet to see any
documentation. At any rate, these codes would only deal with the cluster and
not anything else on the network.

If your ABS light goes out when you turn the key of but comes back on after
the car reaches 5 or so mph, it is most likely speed sensor related. ABS
codes are proprietary.... to retrieve them the scan tool must be capable of
accessing the ABS module. Most bargain scan tools are capable of generic
OBD2 codes only and are useless in retrieving codes from proprietary modules
(these include ABS, HEC, VSM, RCM, PATS, etc...)

Sorry for the acronyms... if anyone wants, I can cobble a list...

I have had an occasional failure with the ABS on my 2003 Explorer. When I
turn off the ignition and then on again, the problem disappears. I brought
the vehicle in for a diag today and they reported that the ABS sensors were
all okay, but they were getting a code L1440 which they tell me they have
never seen before. With Ford being closed today they could not get me more
information. Is anyone familiar with this diag code? Thanks.
